Figured I owe an update -

The dual 370cfm fantech is installed in the configuration shown below


It's quiet, but not "silent". You really dont hear fan-noise, but rather a hollow sound most likely from the metal box enclosure the fan grilles mount into. Thats if you're sitting in silence listening for it. Just having a conversation puts in the background. Watching TV will be no problem.

Like Tony said before, this doesnt cause a vortex pulling all your smoke out instantly. It keeps things steady while I smoke and evacuates the room on the timer afterwards. For @Nature scenario of 4 guys herfing, it wouldn't stand a chance. But for my solo use intent, it'll work.

Flooring installed, lighting installed, fans installed.

Still need to furnish it and kick around extras, but right now a lawn chair works - lol
